' To aZZ 107L077), it nmy concern.-

Be it known that 1. JAMES E. Emacs, of Brooklyn, in the county of Kingsand State of New York, have invented certain new and usefullmpro'reinentsin Shutters for Skylights, of which the following is aspecification.

This invention relates to an improved shutter for'shyiights, by whichthe space below the skylight can be securely shut-off, the shutterforming an effective protection against the spread of lire, as well asa.- safeguard against on glars; and the invention consists ofsslaylightcasing having a horizontal supportingiiange, a shnttcr formedof a series of slats hanged zit one edge and adapted. to be folded up atone side of the casing, one cndslst being 11' to ihe while the oppositeilaitlgo. re opening or closing of the shutter- Slide aceoinplishei'l bywire cords or chains, which from it suitable roller over guideto theontcrn'iost or covering shutter The i: lividual slots are connected withea 2 othe by longitin'linal cordsv which are attached to the llengcs oftiresome. Thewind l' we inz np roller is locked by a paw-iand ratchatdevice. and operated by a hand-crank or other le device. in the'mscompanying drawings, Figure 1 r-egrcsents a plan of my improved slyl'i; htshutter, p; rtly in section, showing the shutter.

' lion; and. Figs. 2 and 3 are veritudinill sections on line :r, li'ig.11, showing; inn shutter rospcctivizly in closed po siiiuz; and l'oldmlup at one side of the casing.

flange, b, which extends over the remaining slats b b when the same arefolded up, as shown in Fig. 3. v

The shutter B is folded npby cords or chains e e, of which the cord e isattached to the flange b of the outermost slat b, and passed over aguide-pnllcy, e, to a pulley, e, on a shaft, E, while the cord e isattached to the opposite edge of the outermost slat Z), and also woundup on the pulley 0, but in opposite direction to the cord 0, as shown inFig. l.

'lheshutter Bis extended, so as to close the casing A,l)y two c0rds,ff,which are attached to the outermost end slat, near the corners of thesaine, and passed over pulleys f and through holes f of the casingftopullcyf on the shaft ll, asishown in Figs. 1, 2, and 3.

The shaft E turns in suitable bearings attached to brackets'at theoutside of the casing A.

On turning the shaft E in one direction the cords ffextend the shutterand place the slats in closed position on the supporting-flange a, asshown in Fig. 3, while the cords c c are simultaneously unwound from thepulley c. On turning the shaft E in opposite direction the shutter isopened by the cords e a and. folded up at one side of thccasingA; asshown in Fig. 3, the cords 7" being unwound from the pulleys f at thesamev time. I

The shaft 1*] is turned by a handcrank, g, or other suitable means, andserves, in conncctionwith the cords o c andffand d d, to fold up orextend thoshnttcr It. When the shutter is folded and raised on its,hinge-connection with the casing, the outermost slat b incloses, by itswider flange, I), the Slots 7) b, as shown in Fig.

The shaft 1' is locked in open or closed position by means of a ratchetand pawl, h lb, the pawlbeing released from the ratchet-wheel wheneverthe shutter is to he folded or extended, and dropped again intotheratchetwhcel when it is desired to retain the shi'itt-cr in folded orextended position.

'lhe-shuttcr forms a. protective device for the shafts or skylightmso asto prevent cllhctually the draft generally produced through the sl tyliht-shnft in cascof fire, and bring thereby the hm within easier control,while it forms, alsrnto some extent-n1. safety device against theentrance of lnlrglars through the skylight.

Having thus described my invention,I claim as new and desire to secureby Letters Patent- 1. The combination, with a skylight casing or shafthaving a supportingfiauge of a. shutter composed of slats,'the innermostend slat being hinged to the casing and the outermost slat provided withaflange extending at right angles thereto, longitudinal cords connectingsaid slats, and mechanism, substantially as de scribed, whereby saidshutter-slats are either folded up at one side of the casing or extendedso as to close the casing, substantially as shown and described.

2. The combinatiom with a skylight shaft or casing having a supportingguide-flange, of a folding shutter formed of slats connected bylongitudinal cords, the innermost slat being hinged to the casing andthe outermost slat provided with a covering-flange, a shaft havingpulleys, cords connecting the outermost slat with one pulley in saidshaft for opening and folding the shutter, and cords, also connecting,the outermost slat with pulleys on said'shait, for extending theshutter and closing the casing, substantially as shown and de- 25scribed. v

3. The combination, with a skylight shaft or casing, A, havingasupporting guide-flange, a, of a folding shutter, B, composed offlanged slats b b, connected by longitudinal cords d d, 30 the innermostslatbeing hinged to one side of the casin while the outermost slat is'rovided wit a wider flange, b, ashaft, F, aving pulleys e andf", cordscc and ff, uizdepulleys c f, and a pawl-and-ratchet evice, 35 h h,substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in pres ence of two subscribing witnesses.

I JAMES E. BRIGGS.
